Research Interests

My research has been focused on understanding the single-particle structure of exotic nuclei. In particular, I have been involved in experiments which have utilized a number of techniques, including gamma-ray and neutron spectroscopy, as well as, direct nucleon transfer reactions with HELIOS, to measure properties of light neutron-rich nuclei. Recently, I have also been involved in an upgrade project for ATLAS aimed at increasing the in-flight beam production of the facility (AIRIS) for reaction, structure, and astrophysics measurements.
